Anchor ProtocolCryptographyLearn how post-quantum cryptography protects every connection, from key exchange to end-to-end encryption.Post-Quantum CryptographyEvery connection between anchors uses post-quantum key exchange, identities and authentication. Every payload is also encrypted a second time, end to end.AdmissionTwo anchors admit each other in three stages before they exchange anything. The stages are a knock, a TLS 1.3 handshake and a post-quantum proof of membership tied to the session.Post-Quantum CryptographyEvery connection between anchors uses post-quantum key exchange, identities and authentication.
